The application of loop-mediated isothermal amplification for detection of common pathogenic bacteria in lower respiratory tract infections

Objective To investigate the spectrum of common pathogenic bacteria of low respiratory tract infection by loop-mediated isothermal amplification(LAMP)of nucleic acid test and to prove the clinical significance of this method.Methods A total of 289 qualified sputum samples from patients with lower respiratory tract infections in Fujian Province were detected by LAMP technique,and then the distribution of pathogenic bacteria was analyzed.The positive cases(the patients whose
